15 Claims;

This invention relates to an improved spinning rin for a ring spinning frame for use in the spinning and twisting of yarn, thread, cord, or the v like. In spinning and twisting by the usual ring andtraveler system, the yarn, thread or the like is fed from a suitable source or supply, such as a package, a drafting device, or artificial flber spinning machine through a ring in the rail of a spinning machine onto a take-up package, such as a bobbin, spool, or cone, which ismounted on a spindle rotated at high speed. The spinning ring carries a traveler which bears frictionally on the ring and through which the yarn passes as it is wound onthe take-up package.

It is the general object of the present invention to provide an improved spinning ringfor use in connection with a rotating take-up package which will facilitate and speed up lacing-up.of

1 rail of a spinning or twisting frame equipped with a plurality of spinning rings according to my invention;

Figure 2 is a front elevation of my improved spinning ring and closing and opening means therefor, the rail being sectioned on line II-II i of Figure l; T

Figure 3 is a modification of the ring shown in Figure 2;

Figure 4 is a, fragmentary plan view of the arrangement shown in Figure 3; and s 1 Figure 5 is a fragmentary plan view of a split spinning ring.

In the drawing, the numeral 2 designates the ring rail of a spinning or twisting frame having a plurality of rings 3 mounted thereon. The spinning rings may be mounted directly in openings provided inthe spinning rail itself for their reception, as illustrated, or, if desired, the rings may be mounted in openings in individual holders projecting from the ring rail and secured thereto by means of bolts or screws.

As shown more particularly in Figures 2 and 3, each ring 3 is provided with a traveler T which moves about the ring and guides the yarn in the usual manner'to a spool or bobbin, or the like take-up package, shown in dotted lines at H) in Figure 1. Ring 3, which is preferably composed of a strong resilient material, and hence has a spring-like action, is non-continuous or split, the

two ends 8 and 9 thereof being separated to form v a gap through which the yarn or the like may be passed to-the take-up package. The split ring \has an external, centrally disposed co-extens ive flange 4. The ends 8 and 9 of the ring may normally tend to spring together, or may tend to spring apart,

In the embodiment of the invention shown in Figure 2, the ends 8 and 9 of the ring normally tend to spring apart and a means is provided for forcing the ends together to form a substantially continuous closed ring in use. As shown in Figure 2 such closing means takes the form of an eccentric 5 which is pivotaly mounted on the ring rail as at 6 adjacent flange 4, as shown more clearly in Figure 1. The eccentric is provided with a handle I by means of which it can be swung against or away from the ring flange to close or'open the gap between the ends 8 and 9 of ring 3.

When it is desired to lace-up the spinning device, using the ring arrangement shown in Figure 2, the yarn is simply passed through the gap in the ring, and threaded through the traveler. The eccentric 5 is pressed against the flange 4 of ring 3, forcing the two ends of the ring into engagement with one another, to form a closed circle, and the yarn is carried by the traveler around the ring, and guided to the rotating takeup package in the usual manner. While. theeccentric is maintained in that position, the ring provided for opening the ring, as required. The

means for forcing the ends 8 and 9 apart to provide a'gap' in the periphery of. the ring takes the form of an eccentric M having a handle l2 and pivotally mounted adjacent flange 4, as at [4. One end of a. rigid strap I3 is pivotally secured to eccentric I lby pin l5, and the other end thereof isispivotally secured to flange 4 of ring 3 by pin -an external flange on said split ring, and means pivotally When it is desired to lace-up the spinning device, using the ring arrangement shown in Figure 3, eccentric l I is moved away from ring 3, pulling strap I3, and hence flange 4 with it, thus forcing the ends 8 and 9 of ring 3 apart to form the desired gap therebetween. The yarn is passed through the gap and threaded through the traveler. Eccentric I I is then moved in the opposite direction, toward ring 4, and the ends 8 and 9 are brought together again to form a substantially continuous closed circle.

The two ends of the split ring may be shaped to any complementary form which will enable them to fit together to form a smooth closure. In the ring illustrated in Figures 2 and 3 each end thereof has the approximate shape of a V, each V being disposed with its axis of symmetry horitogether to form a substantially continuous closed zontal and with their sides parallel, as shown at I and 8. Such a structure is entirely satisfactory because when pressure is exerted against the ring flange, the two V-shaped ends fit in to each other to form a smooth closure which does not interfere with continuous movement of the traveler about the periphery of the ring during the norwithout causing inconvenience or delay to the op-.

erator of the spinning machine. The combination of a split spinning ring and means for closing or opening the same at will has the further distinct advantage that it may be readily adapted to circle.
